The invention discloses a combined linkage folding baby carriage and a folding mechanism thereof, and relates to the technical field of baby carriages. Comprising a front frame, front wheels, rotating parts and a rear frame, the front wheels are symmetrically arranged at the bottom end of the front frame, the rotating parts are connected through a long shaft, the rear frame is arranged on the outer side of the long shaft connected with the rotating parts, and a movable joint is movably installed at one end of the front frame. According to the folding mechanism of the combined linkage folding type baby carriage, three sets of joint sleeves are arranged to be used in cooperation to achieve folding of the baby carriage, a gear is inserted into the inner wall of a special-shaped mounting groove, and convex teeth are meshed with tooth grooves in the outer side of the gear, so that limiting of the first joint sleeve is achieved, the first joint sleeve cannot turn over along a third joint sleeve, and the first joint sleeve cannot turn over along the third joint sleeve; the limiting block plays a role in limiting the first special-shaped protruding rod and the second special-shaped protruding rod, and when limiting of the first special-shaped protruding rod and the second special-shaped protruding rod is relieved, and the first special-shaped protruding rod and the teeth conduct gathering movement, the front frame and the rear frame are folded and stored in a rotating mode.

    本发明公开了一种组合式联动折叠式童车及其折叠机构,涉及童车技术领域。包括前车架、前轮、旋转部、后车架,所述前轮对称设置在前车架的底端,所述旋转部通过长轴连接,所述后车架设置在与旋转部连接的长轴外侧,所述前车架的一端活动安装有活动关节。该组合式联动折叠式童车的折叠机构,通过设置三组关节套进行配合使用,来实现童车的折叠,其中齿轮插接在异形安装槽的内壁,凸齿与齿轮外侧的齿槽啮合,从而实现对第一关节套的限位,第一关节套不能沿着第三关节套进行翻转,限位块起到对异形凸杆一和异形凸杆一限位的效果,当解除异形凸杆一和异形凸杆一的限位,异形凸杆一和齿牙在做聚拢运动的时候,实现前车架和后车架的旋转着折叠收纳。
